Located next to basilica St Castor, in the vicinity of Deutsches Eck in Koblenz, Germany, the temporary pavilion will facilitate diverse events during summer of 2011. Occupying a plot that was previously used as a parking space, the treelike structure holds a pivotal position between The Gardening Show and the surrounding urban fabric. The aim of the project is to create a versatile space suitable for exhibitions, lectures, workshops and spontaneous gatherings of students. The members of Düsseldorf based office One Fine Day commented that one of the important aspects of the design was to educate both students and craftsmen of recent computational design and computer aided manufacturing technology.

The polygonal geometry and manifold symmetries of nearby St. Castor’s stellar vault have been a major inspiration for the project. Together with a rotationally symmetrical order a system of interdependent geometrical relations was defined that was resilient, yet rigorous enough to adapt to specific structural and functional needs. Furthermore the “branching” and inherent “porosity” of the trees’ leafy canopy above has been abstracted into the similarly “porous” pentagonal and rhombic tessellation of the surfaces.

The Pavilion uses the shape of an extruded pentagon instead of a square-box – a simple geometrical “plus” that changes the building’s appearance significantly in relation to a beholder’s standpoint. The partly screen printed glass curtain blurs the interior construction and superimposes it with reflections of the surrounding trees.The lighting changes drastically during the night. An interactive light-installation reacts to movements of the visitors, creating different visual effects.

In October 2011 The Treehugger will be dismantled to then be re-erected on the premises of the Chamber of Skilled Crafts, Koblenz.
